well i was wlking across some standing seam panels and slipped. when i put my hand down to catch myself i slid it right down some drip edge and fillet'd my forearm pretty good. another 1/4 inch to right i would have completely severed the tendon and lost all use of the hand. and another 1/4 inch deeper and i would have cut the main attery. but i got full use of my hand and still have all sensitivity so i got lucky and will make 100 percent recovery
